Apollo offers a platform that combines sales intelligence and execution workflows with a business-to-business (B2B) buyer database of over 270 million verified contacts. The company recently raised $100 million in a Series D round at a $1.6 billion valuation, nearly double its previous, led by Bain Capital Ventures with participation from Sequoia Capital, Tribe Capital, and Nexus Venture Partners — making it one of the first sales tech unicorns minted in 2023.
